Anti-silting method for ship lock passing through high-sand-content large-fall river channel

Abstract

The invention discloses an anti-silting method for a ship lock passing through a high-sand-content large-fall river channel. The device comprises a ship lock, a gate, a lock bottom, a water inlet gateand a water outlet gate, the gate is characterized in that a through gate width whole course is arranged below the gate; independent turn-off and turn-on, the transverse linear water inlet gate and the water outlet gate synchronously move along with the gate; water in the ship lock is injected and discharged; all the operations are realized through a water inlet gate and a water outlet gate; compared with the prior art, the ship lock has the technical advantages that the water injection and drainage processes in the ship lock pass through the linear gate; mainly, horizontal torrent flows in and out along the bottom of the lock to wash sediment settled at the bottom of the lock to enter a suspension state again to be released from the ship lock. Meanwhile, the lock is opened and closed after the water injection and water release processes are completed, resistance of static pressure and dynamic pressure is avoided, and the valve is opened more smoothly in an energy-saving mode.

Description

[0001] 1. Technical field: [0002] The invention relates to a ship lock on a drop water surface, in particular to a method for preventing clogging of a ship lock passing through a river channel with high sand content and large drop. [0003] 2. Background technology: [0004] It is the most common and basic method for inland ships to cross the drop water through ship locks. However, under certain special hydrological, geological and geomorphic environmental backgrounds, there are many specific problems and obstacles in the construction and application of ship locks. For example, the Yellow River in China, a On the one hand, due to the historical siltation of high sediment content, the riverbed in the downstream section is significantly higher than the ground on both banks, making it difficult for cross-navigation channels to cross directly, and it needs to be implemented through ship locks. , so that the passage lock is easy to silt up quickly and lose its function or cause th...

[0004] It is the most commonly used and basic method for inland ships to cross the drop water through ship locks. However, under certain special hydrological, geological and geomorphic environmental backgrounds, there are many specific problems and obstacles in the construction and application of ship locks. For example, the Yellow River in China, a On the one hand, due to the historical siltation of high sediment content, the riverbed in the downstream section is significantly higher than the ground on both banks, making it difficult for cross-navigation channels to cross directly, and it needs to be implemented through ship locks. , so that the passage lock is easy to silt up quickly and lose its function or cause the operating cost to be too high, which makes it difficult for many people in modern times to realize the dream of navigating the entire Grand Canal, and it also becomes the end or starting point of other cross-river shipping
